Title: Manufacture of piston
Inventor: MIYAKE JOJI
IPC: B23K26/00
Filed: 1984-08-06
Abstract: PURPOSE:To increase the wear resistance of ring grooves in an Al alloy piston for an internal-combustion engine to piston rings and to prevent the seizing of the rings by the grooves by cutting the grooves in each alloyed Al layer having a specified composition contg. Mo. CONSTITUTION:The body 1 of a piston for the internal-combustion engine is made of an Al alloy, and the outside of a part corresponding to each of ring grooves 2a, 2b, 2c in which piston rings are fixed is closely coated with an Al alloy 4 contg. 5-15% Mo and 15-20% Si by spraying or other method. The part is heated with high density heat energy such as a laser beam, TIG arc or plasma arc to alloy the Al alloy 4 with Al in the body 1. The alloyed part 3 is mechanically worked to cut a ring groove 2a. Ring grooves 2b, 2c are similarly cut. Since the grooves 2a, 2b, 2c have high heat conductivity, piston rings fixed in the grooves are hardly seized by the grooves, and the wear resistance of the grooves to the rings is increased.

IPC: H01L27/08
Filed: 1987-07-01
Abstract: PURPOSE:To make it possible to form a high impurity concentration region without crystal defects readily in the deep part of a substrate, by implanting silicon ions by a high dosing amount, forming a second amorphous layer reaching the surface of the substrate from a first amorphous layer, and continuing the amorphous layer in the deep part of the substrate to the surface of the substrate. CONSTITUTION:A through SiO2 film 2 and a resist film 3 are formed on a P<-> type Si substrate 1 by thermal oxidation and the like. With the resist film 3 as a mask, phosphorus (P<+>) ions are implanted by a high dosing amount through a hole 4 and the through SiO2 film 2, and a first amorphous layer 6 is formed. Then, silicon (Si<+>) ions with two kinds of implanting energies are implanted through the hole 4 in the resist film 3 by high dosing amounts. Thus, a second amorphous layer 7, which is continued to the surface of the substrate 1, is formed in the upper region of the first amorphous layer 6. Then, heat treatment is performed, and the P<+> implanted region is made active. Thus an (n) well 5 is formed. At the same time, the first and second amorphous layers 6 and 7 are recrystallized. Thus the crystalline property is recovered in the direction of an arrow 9 and reaches the surface. Therefore, crystal defects do not remain in the vicinity of the region, where the first amorphous layer 6 has been present.

Filed: 1978-12-27
Abstract: PURPOSE:To obtain a laser recording film having a high resolution power and a low energy threshold value, by coating a binder of organic substance capable of evaporating a specific coloring matter at a low temperature over the surface of substrate. CONSTITUTION:Coloring matter such as Methylene Blue and Brilliant Green, having a high absorption power in a wavelength region of light from light source used for recording and producing heat through absorption of light, is used for laser beam absorbing material.

Abstract: PURPOSE:To stabilize the generation timing of a trigger pulse constantly by setting a trigger pulse to half the time from the time when the output pulse of a zero-cross detector increases to a specific level to that when it decreases to the same level using a trigger pulse generation circuit. CONSTITUTION:After a CPU 10 and a zero cross detector 12 of the title device are actuated and the rising point of a zero-cross detection pulse ZCR is detected by the CPU 10, counting of a timer 11 is initiated.
